Here are some fix that i'm currently use for get better performance.
Fix 1:
Make sure your game updated to update 17 (patch 5.0) this patch makes minor performance change to the game and for me this is the best patch to use.
Fix 2:
Download this FPS FIX and extract it to your game directory, it should be in the same folder as rerev2.exe
Fix 3:
Go to your config.ini
for example c:\users\yourusername\appdata\local\capcom\resident evil revelations2\
and put this on [GRAPHICS] section
TextureMipLimite=2
TextureMipLimit=2
Fix 4: Turn off vsync in the game and turn triple buffering with your nvidia control panel or amd radeon setting. or use d3doverider for force triple buffering.
Fix 5: When start the game, then press alt tab to minimze it, right click on taskbar and select task manager and change rerev2.exe priority to high.
